If an hour is equal to 1, then we know that the answer is more than 3. 12 minutes is equal to 1/5 of an hour, and if we add 3 and 1/5, we get the answer.

3 1/5

Answer:

Jake's running time as a decimal is:

3.2 hours

Step-by-step explanation:

We are given that:

Jake completed a marathon race 3 hours and 12 minutes.

We know that:

1 hour= 60 minutes

1 minute= 1/60 hour

12 minutes = 12/60 minutes

                  = 0.2 hour

3 hours and 12 minutes= (3+0.2) hours

                                      = 3.2 hours

Hence, Jake's running time as a decimal is:

3.2 hours

Which pairs of angles are alternate interior angles? Select all that apply.
andrezito [222]
<h3>Answers: Choice A and Choice C</h3>

Explanation:

Think of the vertical lines as train tracks (the metal rails).

Stuff between the rails are interior angles.

Angles 3 and 6 are one pair of alternate interior angles because they are on alternating sides of the transversal line. The other pair of alternate interior angles are angles 4 and 5.

Alternate interior angles are congruent when we have parallel lines like this.

Use logarithmic differentiation to find dy/dx
liq [111]

Answer:

dy/dx  =  (x^2 - 3)^sin x [2x sin x/ (x^2 - 3) + cos x ln(x^2 - 3)]

Step-by-step explanation:

y = (x^2 - 3)^sinx

ln y = ln  (x^2 - 3)^sinx

ln y = sin x * ln (x^2 - 3)

1/y * dy/dx  =   sin x * {1 / (x^2 - 3)} * 2x + ln(x^2 - 3) * cos x

1/y dy/dx =  2x sin x/ (x^2 - 3) + cos x ln(x^2 - 3)

dy/dx  =   [2x sin x/ (x^2 - 3) + cos x ln(x^2 - 3)] * y

dy/dx  =  (x^2 - 3)^sin x [2x sin x/ (x^2 - 3) + cos x ln(x^2 - 3)]

Find the least common denominator for the group of fractions.<br> 5/12, 9/14, 2/5, 1/10
makkiz [27]

9514 1404 393

Answer:

  420

Step-by-step explanation:

The prime factors of each denominator are ...

  12 = 2²×3

  14 = 2×7

  5 = 5

  10 = 2×5

The unique factors are 2²×3×5×7 = 420.

The least common denominator of these fractions is 420.

_____

<em>Additional comment</em>

  • 5/12 = 175/420
  • 9/14 = 270/420
  • 2/5 = 168/420
  • 1/10 = 42/420
